IMPROVEMENT IN HORSESHOES.

Specification forming part of Letters Patent No. 123,404, dated February6, 1872.

Specification describing a new and Improved Horseshoe, invented byTHOMAS KING- HORN and ROBERT KINGHORN, of Morgan, in the county ofAshtabula and State of Ohio.

Our invention consists of a horseshoe with joints about half-way betweenthe heel and toe, and India rubber springs arranged to force the heelsoutward when attached to expand feet contracted at the heel.

Figure l is a plan of the bottom of our improved shoe and sponge-holder,and Fig. 2 is a section of the shoe on the line w .r of Fig. 1.

Similar letters of reference indicate corresponding parts.

The two sides of the horseshoe are jointed at B so as to approach to orrecede from each other at the heel, and provided with projections 0,having cavities adapted for holdinga spring, D, on each side, in suchmanner that, being contracted by moving the heels toward each other whenthe shoe is attached to the foot, will constantly tend to spread thefoot at the heel by their action thereon, as will be clearly understoodby inspection of the drawing. The projections O are so placed on theinner side of the bar forming the shoe as not to rise so high or extendso low as to interfere in any way with the wearing of the shoe. Thesponge-holder consists of the piece of leather E, formed mainly inoutline like the inner lining of the shoe, but a little larger, with adepression at F for the frog, and provided with the metal clips G,having an upper prong, I, and a lower one, H, which engage the inneredge of the shoe above and below, as shown, to hold the said piece E inposition, one of said clips being near each heel, and another at thetoe. The leather is sprung, to contract it when being introduced, andthe clips are engaged with the shoe.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination of the springs D and lugs b,with the jointed shoe, substantially as speciiied.
